Japanese counters are the silent killer of fluency. Why does a rabbit share its counter with birds? Why does a movie use 本 like a pencil? Why does "ippon" become "nihon" when the number changes? [日语数字上手] is not another generic Japanese app. It’s a focused counter trainer that forces your brain to stop translating and start reacting.
